Description
Durch eine Zugabe von Vernetzern in die von Fall zu Fall einzustellenden Dosierungen wird der Silikonkautschuk in Silikongummi umgewandelt, durch Verdünnen mit Lösungsmitteln die Viskosität erniedrigt und durch Zugabe von Thixotropierungsmitteln eine von der Scherbeanspruchung abhängige Verdückung eingestellt.By adding crosslinkers to the dosages to be set on a case-by-case basis, the silicone rubber is converted to silicone rubber, the viscosity is lowered by diluting with solvents, and a shear stress dependent heel is adjusted by the addition of thixotropic agents.
Nach Verdunsten des Lösungsmittels und Umsetzung des Vernetzers bildetsich ein Überzug mit den geforderten Eigenschaften, wobei diese Phase zweckmäßigerweise durch Temperaturerhöhung beschleunigt werden kann. Um die Wirkung desAfter evaporation of the solvent and reaction of the crosslinker bildetsich a coating with the required properties, this phase can be expediently accelerated by increasing the temperature. To the effect of
Thixotropierungsmittels voll zu entfalten, ist eine gute, aber schonende Verteilung in der Lösung erforderlich, was zum Beispiel durch Benetzung mit einem Teil des Lösungsmittels vor der Zugabe erfolgen kann.Full unfolding of thixotropic agent requires a good but gentle dispersion in the solution, which can be done, for example, by wetting with a portion of the solvent prior to addition.
Die Lösung des Silikonkautschuks mit dem Thixotropierungsmittel kann im dichtschließenden Behälter auf Vorrat hergestellt werden. Erst unmittelbar vor Anwendung wird der Vernetzer zu einem dem unmittelbaren Bedarf angepaßten Ansatz zudosiert und untergerührt.The solution of the silicone rubber with the thixotropic agent can be prepared in the tightly sealed container in stock. Only immediately before application, the crosslinker is added to an immediate needs adapted approach and mixed.
Das Aufbringen des erfindungsgemäßen Überzuges auf das Gipsmodell erfolgt durch Sprühen oder vorzugsweise durchThe application of the coating according to the invention on the gypsum model by spraying or preferably by
Tauchen, da im letzteren Fall die Einhaltung der Schichtdicke am besten möglich ist.Diving, since in the latter case the adherence of the layer thickness is best possible.
An Hand eines Ausführungsbeispieles soll die Erfindung näher erläutert werden.With reference to an embodiment of the invention will be explained in more detail.
100 Teile kaltvulkanisierende Silikonkautschukpaste 60 Teile Äthylazetat und 1 Teil feindisperse Kieselsäure100 parts of cold vulcanizing silicone rubber paste 60 parts of ethyl acetate and 1 part of finely dispersed silica
werden innig vermischt, wobei 20 Teile Äthylazetat mit der Kieselsäure getrennt vor Zugabe vorgemischt werden. Unmittelbar vor Benutzung werden 4 Teile Vernetzer untergerührt, die Gipsmodelle mit der Lösung allseitig umspült und zum Trocknen und Vulkanisieren 1 Stunde lang im Trockenschrank bei 1000C aufgehängt.are intimately mixed with 20 parts of ethyl acetate are premixed with the silica separately before addition. Immediately prior to use, 4 parts of crosslinking agent are stirred in, the plaster models are lapped with the solution on all sides and hung for drying and vulcanization for 1 hour in a drying oven at 100 ° C.
In einem weiteren Ausführungsbeispiel der Erfindung werden 100 Teile Silikonkautschukpaste und 75 Teile Äthylazetat miteinander vermischt, 4 Teile Vernetzer untergerührt und die Gipsmodelle in diese Lösung getaucht. Nach Lufttrocknung von 24 Stunden können die Modelle weiterverwendet werden.In a further exemplary embodiment of the invention, 100 parts of silicone rubber paste and 75 parts of ethyl acetate are mixed together, 4 parts of crosslinking agent are stirred in and the plaster models are immersed in this solution. After air drying for 24 hours, the models can continue to be used.
